Back scratcher



FIG. 1 is a front elevational view of a design for a back scratcher.

FIG. 2 is a mirror image of the backscratcher shown in FIG. 1.

FIG. 3 is a top view looking down on the top of the back scratcher; and,

FIG. 4 is a bottom view looking up from the bottom of the backscratcher. 

I claim the ornamental design for a back scratcher, as shown and described.
